The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.
Oxygen uptake (or consumption) is a measure of a person’s ability to take in oxygen and deliver it to the working tissues, and the ability of working tissues to use oxygen. During low-intensity exercise with a constant power output, oxygen uptake increases for the first few minutes until a steady state of uptake is reached.
Coaches can also benefit from understanding the concepts of positive and negative reinforcement and positive and negative punishment as they relate to motivation. Although coaches use a mixture of both reward and punishment, using rewards and a positive approach is arguably the best approach because it focuses on what athletes should do and what they did right.
High chronic workloads have been shown to be associated with a reduced risk of non-contact, soft tissue injuries, while large spikes in acute training loads have been associated with an increased risk of these types of injury. Analyzing the acute:chronic workload ratio allows a coach to optimize training for the athlete and to continue in advancing fitness goals without overtraining.
